About This Course

NexYouth Eco Literacy: From Environmental Systems to Youth Action is a structured online learning program for students who want to understand environmental issues beyond basic awareness.

Environmental problems are often described through simple messages: recycle more, use less plastic, save the planet. This program goes deeper. Students explore how climate change, biodiversity loss, water pollution, air pollution, plastic packaging, fast fashion, and environmental justice are connected through larger systems of human behaviour, technology, policy, economics, and ecological change.

Through this course, students learn how environmental problems develop, who they affect, and what realistic youth-led action can look like.

By the end of the program, students will be able to explain key environmental systems, analyze causes and impacts, recognize unequal environmental burdens, and design a practical action plan grounded in course concepts.

Lesson 1 — Environmental Systems and Planetary Limits
LessonReading · Video · Task
▼

Overview

Environmental learning is not just about individual habits. Climate change, biodiversity loss, freshwater stress, land-use change, pollution, and ocean changes are connected parts of one Earth system. This lesson introduces planetary boundaries, a framework scientists use to describe the limits that help keep Earth stable for human life. The Stockholm Resilience Centre describes planetary boundaries as nine critical global processes that regulate Earth's stability and resilience.

  • Why it matters for people, not just nature

Lesson 2: Climate Change — Evidence and Impacts
LessonReading · Video · Task
▼

Overview

You may already know that climate change is serious. This lesson focuses on a better question: how do scientists know it is happening? Students examine multiple lines of evidence — rising global temperatures, warming oceans, shrinking ice sheets, and sea-level rise. NASA explains that the evidence for rapid climate change is compelling across multiple indicators, not based on one weather event.

  • Sea-level rise

For each one, write what is being measured and why it matters.

Lesson 3 — Biodiversity and Ecosystem Services
LessonReading · Video · Task
▼

Overview

Biodiversity is not just about saving animals. It supports the systems humans depend on — food, clean water, pollination, soil health, flood protection, and climate stability. The IPBES Global Assessment reported that around 1 million animal and plant species are threatened with extinction, many within decades.

Lesson 4 — Eutrophication, Dead Zones, and Harmful Algal Blooms
LessonReading · Video · Task
▼

Overview

Water pollution is not always visible as trash floating on the surface. One major water problem is eutrophication — when excess nutrients such as nitrogen and phosphorus enter water systems. These nutrients can trigger dense algal blooms, reduce water clarity, block sunlight, lower oxygen levels, and create dead zones where aquatic life struggles to survive. Students will learn the chain reaction from land-based pollution to ecosystem damage, and why water quality problems are often caused by activities far upstream.

Lesson 5 — Air Pollution and Human Health
LessonReading · Video · Task
▼

Overview

Environmental issues are not only about forests, oceans, and wildlife — they are also about the air people breathe. Air pollution can affect the lungs, heart, brain, and overall health. WHO explains that air pollution enters mainly through the respiratory tract and can cause inflammation, oxidative stress, immunosuppression, and disease in multiple organs.

Lesson 6 — Plastic Packaging and Material Systems
LessonReading · Video · Task
▼

Overview

Plastic pollution is not only a littering problem. It is connected to material choices, packaging design, convenience, production, waste systems, recycling limits, and pollution leakage. This lesson uses plastic packaging as a case study because packaging is everywhere and often used briefly before becoming waste. The goal: understand why plastic is useful, why it becomes a problem, and why recycling alone cannot fix the system.

  • What would a better packaging design look like?
👕
Lesson 7 — Fast Fashion and Consumption Footprints
LessonReading · Video · Task
▼

Overview

Environmental impact is often hidden inside everyday products. Clothing is a clear example. Fast fashion encourages quick production, low prices, frequent buying, and fast disposal. This creates impacts through textile production, dyeing, washing, microplastic fibres, transport, and landfill waste. The European Parliament explains that textile production is estimated to cause about 20% of global clean water pollution, mainly from dyeing, and that one laundry load of polyester clothing can release 700,000 microplastic fibres.

Lesson 8 — Environmental Justice
LessonReading · Video · Task
▼

Overview

Environmental problems do not affect everyone equally. Some communities face more pollution, weaker protection, less green space, unsafe water, or higher heat risk. This lesson asks students to think about exposure, power, evidence, and decision-making. Canada's National Strategy Respecting Environmental Racism and Environmental Justice Act became law on June 20, 2024, and the Government of Canada states that advancing environmental justice requires addressing environmental racism and unequal protection.

Lesson 9 — From Environmental Understanding to Action
LessonReading · Video · Task
▼

Overview

A strong environmental action plan is not just "raise awareness." It must identify a specific problem, use evidence, explain who is affected, propose a realistic action, measure results, and admit limitations. Project Drawdown's primer is useful because it teaches students to judge climate solutions by how they work, whether they reduce emissions or remove carbon, and how their impact can be classified.

  • Who is affected?
  • What action is realistic for a student?
  • How could impact be measured?
  • What are the limits of the action?
